DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the implementation modes and the accompanying drawings. Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0028] refer to Figures 1 to 6 ,like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides an oil-water separation device, including a separation box 1, wherein the separation box 1 has a filtering area, a sedimentation area 3, a static area 4, an oil-water separation area 5, an oil liquid area 6 and a drainage area 7. The residual material, palm oil, and a mixture of oil, water and water reserved by the main engine are transported to the filtering area through a gear pump for filtration. A filter screen 2 is arranged on the filtering area, and the filter screen 2 can filter the residual material, palm oil, and the mixture of oil, water and water. The sedimentation area 3 is located below the filter screen 2. The pressure impact during oil inflow causes part of the residual material, oil and water to be stratified. The sedimentation area 3 can eliminate the impact force and make the liquid surface in a micro-motion and stratified state; the static area 4 and the oil-water separation area 5 are arranged in sequence on one side of the sedimentation area 3. In the static area 4, the residual material, oil and water can be separated according to the pressure. The oil is driven to move to the oil-water separation area 5 according to the direction of water flow, so that the oil and water are separated according to material density, temperature, mutual collision and other phenomena; the oil area 6 and the drainage area 7 are arranged side by side on one side of the oil-water separation area 5. When the oil after oil-water separation in the oil-water separation area 5 is stored to a certain amount of oil, the flow rate is adjusted by the sonar liquid level detector. When the set liquid level is reached, the oil pump automatically transports the oil flowing into the oil area 6 through the oil-water separation area 5 to the peripheral oil storage tank, so as to achieve the purpose of setting the oil output according to demand; a steam pipe 8 is also arranged in the separation box 1. The steam pipe 8 is extended out of the separation box 1 after circling the separation box 1. The steam pipe 8 plays a heating role, so that objects with different properties, densities and temperatures can be separated from each other under heating.

[0029] Preferably, in the embodiment of the present application, a steam heating pneumatic valve is provided at the inlet 81 of the steam pipe 8 to control the heating condition of the steam pipe 8. The steam pipe 8 enters the separation box 1 from the right side of the drainage area 7, passes through the oil-water separation area 5, the static area 4 and the sedimentation area 3 in sequence, bends in the sedimentation area 3, and then passes through the static area 4, the oil-water separation area 5 and the oil-liquid area 6. Finally, the outlet 82 of the steam pipe 8 passes through the separation box 1 from the right side of the oil-liquid area 6.

[0030] In the embodiment of the present application, the outlet 82 is used for steam discharge.

[0031] Preferably, in the embodiment of the present application, in order to improve the heating efficiency, two steam pipes 8 spaced apart from each other are provided in the separation box 1 .

[0032] In the embodiment of the present application, a temperature probe 51 and a liquid level probe 52 are arranged above the oil-water separation zone 5, and the temperature probe 51 and the liquid level probe 52 are arranged at intervals.

[0033] In the embodiment of the present application, the temperature probe 51 is used to detect the liquid temperature in the oil-water separation zone 5. The temperature probe 51 cooperates with the thermal resistor so that the temperature controller controls the automatic opening and closing of the steam pneumatic valve, which can automatically heat to the set value and ensure the temperature of the oil-water separation zone 5.

[0034] In the embodiment of the present application, the liquid level probe 52 is used to detect the liquid height in the oil-water separation area 5. When the liquid is at a low water level, the liquid level probe 52 controls the steam heating pneumatic valve to close, thereby achieving energy saving and preventing high temperature danger;

[0035] When the liquid is at a high water level, in this state, the amount of oil is above 3 / 5 of the oil-water separation zone 5, that is, the oil is about 50mm. When the amount of water exceeds 2 / 3, the liquid level probe 52 controls the high water level probe to be conductive (water-oil conductivity), starts the strong exhaust actuation angle seat valve, and automatically closes the strong exhaust actuation angle seat valve after reaching the standard (that is, lower than the set value of the strong exhaust liquid level detection probe) to prevent the water level in the oil-water separation zone 5 from entering the oil zone;

[0036] When a large amount of water is used, the liquid is in an over-water level, which will cause the water level in the oil-water separator area 5 to exceed the position of the oil-liquid separation port 63, causing the liquid inlet pump (T1) used to control the flow of the oil-water mixture entering the present application to stop working, the high water level alarm on the operation panel, and the forced exhaust angle seat valve to open for drainage, and remind personnel to pay attention to the water level and liquid inlet volume to prevent a large amount of water from entering the oil-liquid area 6 and causing the separated oil and water to mix again.

[0037] Preferably, the high water level probe adopts a liquid level controller, model 61F-G2NN of Omron.

[0038] In the embodiment of the present application, an oil high level probe 62 is arranged above the oil area 6, and an oil area drain pipe 61 is connected to the bottom of the oil area 6. The oil area drain pipe 61 is controlled by the oil outlet pump. The oil high level probe 62 can detect the oil height in the oil area 6. When the oil is at a set high liquid level, a high liquid level signal is given to the liquid level controller, and the liquid level controller sends a pneumatic valve action to the solenoid valve to start the oil outlet pump for control, thereby achieving timed and quantitative oil discharge, avoiding the oil temperature fluctuation of the oil pan caused by excessive oil volume and high pressure, thereby making it safer to use.

[0039] In the embodiment of the present application, a plurality of side panels are provided in the separation box 1, thereby dividing the separation box 1 into a sedimentation area 3, a static area 4, an oil-water separation area 5, an oil-liquid area 6 and a drainage area 7, and an oil-liquid separation port 63 is provided on the side panel between the oil-water separation area 5 and the oil-liquid area 6, for the oil to enter the oil-liquid area 6 from the oil-water separation area 5.

[0040] like Figure 1 and Figure 6As shown, the rear end of the side plate between the sedimentation area 3 and the static area 4 has a first channel 31 connecting the sedimentation area 3 and the static area 4, and the front end of the side plate between the static area 4 and the oil-water separation area 5 has a second channel 42 connecting the static area 4 and the oil-water separation area 5. The first channel 31, the static area 4 and the second channel 42 cooperate to form a Z-shaped channel for the flow of oil. Specifically, after the mixture enters the sedimentation area 3, it first flows from the sedimentation area 3 into the static area 4 through the first channel 31, and then flows from the static area 4 into the oil-water separation area 5 through the second channel 42.

[0041] In the embodiment of the present application, a static zone drain pipe 41 is connected to the bottom of the static zone 4 , and the static zone drain pipe 41 is used for draining sewage and cleaning the static zone 4 .

[0042] In the embodiment of the present application, a first oil-water separation zone drain pipe 53 is provided at the bottom of the oil-water separation zone 5 for cleaning and draining the oil-water separation zone 5 .

[0043] In the embodiment of the present application, a second oil-water separation zone drain pipe 54 is connected to the side of the oil-water separation zone 5, the first oil-water separation zone drain pipe 53 and the second oil-water separation zone drain pipe 54 both extend outside the separation box 1, and two branch pipes 531 are connected to the bottom of the first oil-water separation zone drain pipe 53. The second oil-water separation zone drain pipe 54 is connected to the second drainage zone drain pipe 73, so that the water at the bottom of the oil-water separation zone 5 will enter the drainage zone 7 through the second oil-water separation zone drain pipe 54 and the second drainage zone drain pipe 73, which is used for cleaning and discharging sewage in the drainage zone 7, thereby achieving the purpose of centralized discharge.

[0044] In the embodiment of the present application, a first drainage area drain pipe 71 is connected to the side of the drainage area 7 , and a second drainage area drain pipe 73 is provided at the bottom of the drainage area 7 for manually draining sewage and cleaning the drainage area 7 .

[0045] like Figure 1 and Figure 5 As shown, a water level regulator 72 is provided in the drainage area 7. The water level regulator 72 is controlled by a central adjusting screw. When the central adjusting screw is rotated counterclockwise, the water level regulator 72 moves downward and the water level is low. Conversely, the water level rises, so that the drainage liquid level reaches a state where the water level and the oil level are parallel and the oil level is higher than the oil-liquid separation port 63. When the oil level is higher than the oil-liquid separation port 63, the oil level can enter the oil area to achieve the effect of oil-water separation. The bottom of the water level regulator 72 is connected to a regulator drain pipe 721, which can discharge excess water in the drainage area 7.

[0046] like Figure 4As shown, a plurality of covers are arranged on the top of the separation box 1, and the covers can respectively cover the filtering area, the sedimentation area 3 and the static area 4, the oil-water separation area 5, the oil liquid area 6 and the drainage area 7, thereby making it safer to use during operation.

[0047] like Figure 3 and Figure 5 As shown, a perspective window 9 is provided on the front side of the separation box 1, through which the separation of oil and water in the oil-water separation area 5 can be observed. After being heated by the steam pipe 8, the oil-liquid mixture will gradually be divided into three layers, namely, an oil layer, an oil-water mixed layer and a water layer from top to bottom. With the difference in separation time, temperature and density, the oil-water mixed layer will gradually be separated continuously until the liquid inlet stops, and the oil-water mixed layer will be completely, continuously and automatically separated. Therefore, the oil will finally be completely separated into an oil layer and a water layer, and the oil will flow into the oil area 6 through the oil through port 63 for recovery.

[0048] Preferably, in the embodiment of the present application, the bottom of the separation box 1 is supported by a plurality of columns 11 .

[0049] Working principle: The oily wastewater is transported to the filter area through a gear pump, and the filter screen 2 filters the particles. The filtered oil-water mixture flows into the sedimentation area 3, is precipitated in the sedimentation area 3, and then enters the static area 4 through the first channel 31 for static, and then enters the oil-water separation area 5 through the second channel 42 after static. The static area 4 and the oil-water separation area 5 can simultaneously reduce the impact of the original liquid on the oil-water separation area 5 to achieve the oil-water separation effect. The mixture in the oil-water separation area will be divided into three liquid levels of water liquid-oil-water mixed liquid-oil liquid (water content within 0.1%) in the oil-water separation area 5. Since the second oil-water separation area drain pipe 54 is connected with the first drainage area drain pipe 71, according to the connecting vessel In principle, the water surface will be connected with the drainage area 7, that is, the excess water (oil content is within 0.3%) will be discharged to the drainage area 7, and then discharged through the regulator drain pipe 721. The height of the oil and water surface can be adjusted by the water level regulator 72, so that the oil will flow into the oil area 6 through the oil-liquid separation port 63 of the oil-water separation area, and then the oil will be recovered by the automatically controlled gear pump to achieve the separation of oil and water. When the oil is recovered, when the oil level reaches the length of the oil high level probe 62 (there is a potentiometer in the instrument box to adjust the liquid level), a digital signal is output to the intermediate relay, and the oil outlet pump is started by timing to start oil discharge, and the oil outlet pump stops after the delay time.

[0050] In summary, the present application adopts a lower liquid level control heating device (i.e., the temperature controller controls the heating temperature), a high liquid level water discharge device (i.e., the solenoid valve + pneumatic angle seat valve controls the discharge of water), an oil-water flow instantaneous increment control device (i.e., the oil-water inlet gear pump control) and sonar detection to automatically control the oil outlet pump. It has a high degree of automation and the work is carried out in an orderly manner. In addition, the present application adopts stainless steel 304 and 316L materials as a whole, which have good materials, good quality, and few faults. It adopts Schneider and Omron electrical appliances and has good working conditions. In addition, the use of Delta inverter to control the oil outlet pump can reduce the safety risks caused by excessive oil pressure, making it safer to use.

[0051] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the embodiments of the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
